I wish this were a post about a mod to add Red Square to Civ V as a wonder... but no. Unfortunately, I just noticed that I've been getting the red and white checkers playing Civ V on 10.8. I don't think I had this problem before, although I had read about others experiencing it. After some research, the squares may be due to overheating. I checked my temp and my GPU die was running at over 172 F. I shut off Civ V and I have it down to 166... but it still seems to be running really hot for not doing much. I noticed that some of you have issues with running on 10.8. I didn't notice it being much slower than usual, but this overheating thing is a concern. Can anyone tell me what temps they are running? I'm on an iMac 2.7 i5 with 12 GB ram and Radeon 6770M 512MB. Thanks!
